Abstract
A new species of leaf-mining moth described here as Micrurapteryxbaranchikovi Kirichenko, Akulov & Triberti, sp. nov. was detected in large numbers feeding on Thermopsislanceolata (Fabaceae) in the Republic of Khakassia (Russia) in 2020. A morphological diagnosis of adults, bionomics and DNA barcoding data of the new species are provided. The developmental stages (larva, pupa, adult), male and female genitalia, as well as the leaf mines and the infestation plot in Khakassia are illustrated; the pest status of the new species in the studied region is discussed. Additionally, parasitism rate was estimated, the parasitoid wasps reared from pupae of the new species were identified (morphologically and genetically) and illustrated . Among them, one ichneumonid, Campoplexsp. aff.borealis (Zetterstedt) and two braconids, Agathisfuscipennis (Zetterstedt) and Illidopssubversor (Tobias et Kotenko), are novel records for the Republic of Khakassia. Furthermore, they are all documented as parasitoids of Gracillariidae for the first time. The DNA barcode of A.fuscipennis is newly obtained and can be used as a reference sequence for species identification.
Highlights
No Micrurapteryx species has a Holarctic distribution (De Prins and De Prins 2021). All these species were described in 19th and 20th centuries, except M. tibetiensis that was described from China in 2013 (Bai 2013) and M. caraganella that was redescribed from Siberia (Russia) in 2016 (Kirichenko et al 2016)
We describe a new species, Micrurapteryx baranchikovi Kirichenko, Akulov & Triberti, sp. nov., reared from Thermopsis lanceolata R.Br. (Fabaceae) in the Republic of Khakassia, Russia
The maximum likelihood tree based on COI sequences shows six clusters with 98–100 bootstrap support that match up with Barcode Index Numbers (BINs) (Fig. 2)
Summary
The majority are known from some parts of Eurasia: M. bidentata Noreika, 1992, M. bistrigella (Rebel, 1940), M. caraganella (Hering, 1957), M. fumosella Kuznetzov & Tristan, 1985, M. gerasimovi Ermolaev, 1982, M. gradatella (Herrich-Schäffer, 1855), M. kollariella (Zeller, 1839), M. parvula Amsel, 1935, M. sophorella Kuznetzov, 1979, M. sophorivora Kuznetzov & Tristan, 1985, M. tibetiensis Bai & Li, 2013, and M. tortuosella Kuznetzov & Tristan, 1985. No Micrurapteryx species has a Holarctic distribution (De Prins and De Prins 2021). All these species were described in 19th and 20th centuries, except M. tibetiensis that was described from China in 2013 (Bai 2013) and M. caraganella that was redescribed from Siberia (Russia) in 2016 (Kirichenko et al 2016)
